[0002] A rotary feeder, also known as a rotary feeder, is a type of material conveying equipment widely used in industries such as mining, building materials, and chemicals. It uses a rotating spiral scraper or ring hopper to continuously and smoothly convey materials from the bottom of the container to the discharge port below, achieving automated feeding. This equipment offers advantages such as compact structure, stable operation, and high conveying efficiency. It effectively prevents material blockages, improving production efficiency and product quality. Furthermore, rotary feeders feature adjustable material flow. By adjusting the spiral speed or turntable angle, the material flow rate can be precisely controlled to meet diverse production needs.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution of a lime quantitative addition and anti-blocking device, comprising a feeder housing 1, a ring hopper 2 movably installed in the feeder housing 1, a first motor 4 fixedly installed on one side of the feeder housing 1, a driving shaft 3 provided between the ring hopper 2 and the first motor 4, a knocking seat 5 and a protruding block 6 fixedly installed on the side wall of the ring hopper 2, and the knocking seat 5 corresponds to the protruding block 6 one to one, a knocking mechanism 7 fixedly installed on the side wall of the feeder housing 1, a control mechanism 8 fixedly installed on the feeder housing 1, the ring hopper 2 can be driven to rotate by the first motor 4 to realize lime feeding, the ring hopper 2 can be vibrated by the coordinated use of the knocking mechanism 7 and the control mechanism 8, and the dust accumulated inside the ring hopper 2 after the vibration of the ring hopper 2 falls down to prevent lime from being blocked in the ring hopper 2.

[0023] like Figure 3 and Figure 4As shown, the knocking mechanism 7 includes a mechanism housing 701 fixedly mounted on the side wall of the feeder housing 1, a second motor 705 fixedly mounted in the mechanism housing 701, an eccentric wheel 702 fixedly mounted on the output of the second motor 705, a connecting rod 703 movably mounted on the eccentric wheel 702, a reciprocating metal column 706 movably mounted on the end of the connecting rod 703, a knocking rod 707 movably mounted on the front end of the mechanism housing 701, a positioning frame 704 is provided in the mechanism housing 701, and the reciprocating metal column 706 is movably mounted in the mechanism housing 701 through the positioning frame 704.

[0024] Specifically, the second motor 705 can drive the eccentric wheel 702 to rotate. During the rotation of the eccentric wheel 702, the connecting rod 703 will drive the reciprocating metal column 706 to reciprocate. During the reciprocating motion of the reciprocating metal column 706, the knocking rod 707 will reciprocately hit the knocking rod 707, causing the knocking rod 707 to knock the knocking seat 5 on the annular hopper 2. The annular hopper 2 will vibrate when knocked, causing the dust accumulated inside the annular hopper 2 to fall down, thereby preventing lime from being blocked in the annular hopper 2.

[0025] like Figure 3 and Figure 5 As shown, a knocking seat 5 and a protruding block 6 are fixedly mounted on the side wall of the annular hopper 2, and the knocking seat 5 corresponds to the protruding block 6 one by one. The control mechanism 8 includes a sliding sleeve 804 fixedly mounted on the feeder housing 1, and a button switch 806 is movably mounted in the sliding sleeve 804.

After the feeder housing 1 is installed at the bottom of the lime silo, the annular hopper 2 can be driven to rotate by the first motor 4 to realize lime loading. Once the lime accumulates in the annular hopper 2, the screw 803 can be rotated and driven. After the screw 803 is rotated and driven, it will drive the button switch 806 to move forward a short distance. When the blockage point on the annular hopper 2 turns downward, the protruding block 6 will press the button switch 806, thereby starting the second motor 705 when the knocking rod 707 is aligned with the knocking seat 5. After starting the second motor 705, it will drive the eccentric wheel 702 Rotation, since one end of the connecting rod 703 is movably mounted on the eccentric wheel 702, and the other end of the connecting rod 703 is movably mounted on the reciprocating metal column 706, the connecting rod 703 will drive the reciprocating metal column 706 to move back and forth during the rotation of the eccentric wheel 702, and the reciprocating metal column 706 will reciprocately hit the knocking rod 707 during the reciprocating motion, so that the knocking rod 707 knocks the knocking seat 5 on the annular hopper 2, and the annular hopper 2 will vibrate when knocked, causing the dust accumulated inside the annular hopper 2 to fall down, preventing lime from being blocked in the annular hopper 2, and the knocking rod 707 will only hit the knocking seat 5, thereby reducing the damage to the annular hopper 2.
